Do It Yourself Solar Panels – DIY Solar Panels How I built a solar panel for 0 – You can too Mike Davis - no hidden costs In this article I am going to describe how to build a photo voltaic solar panel for a fraction of the price you would pay a manufacturer. I’ll show you how inexpensive materials and common tools can be used to make panels that rival commercial products in power production, but blow them away on price. Several years ago I bought a remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. Initially I built a wind turbine. I do get well over 300 sunny days a year on the property though, so solar power seemed like the obvious choice to supplement the turbine. The finished solar panel Really a solar panel is just a box that holds an array of solar cells. Seconds from e bay However it takes a lot of cells to make a useful amount of power, and being largely glass, they are very fragile. A 3 X 6 mono-crystalline solar cell from Ebay Another tip.

Solar Thermal – An Old Concept for Today’s World | GreenBuildTVGreenBuildTV Some people think the concept of solar thermal is radically new. Truth is – people have been using the power of the sun for decades to provide hot water. But catching the sun’s rays hasn’t always been an easy task. Early on, people used a black-painted water tank, mounted on a roof, to gather the sun’s rays. A few of the more common solar thermal collectors today include: the flat plate, evacuated tube, and parabolic trough. Flat Plate Collectors Developed and in use since the 1950′s, flat plate collectors remain the most common type of solar thermal collector. Plates are usually constructed of copper or aluminum, though some polymers can also be used, especially in climates susceptible to freezing. Evacuated Tube Collectors Evacuated tube collectors have been in use for the last thirty years. This protection against heat loss, though, can work against evacuated tubes in snowy conditions, when they lack the heat needed to keep snow from accumulating upon the collector. Parabolic Trough

DIY Solar Projects Part 1: Build a Solar Heater Using Recycled Cans A few months ago we did an article about Cansolair Inc’s brilliant solar home heating solution that uses recycled aluminum cans in a forced convection solar heating unit. These units work by pulling cool air from a room, passing it through a panel of aluminum cans that are heated by the sun, and blowing the heated air back into the room. Just about anyone can make one of these heaters, and they can be constructed from mostly recycled materials.

How I built an electricity producing wind turbine Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. I found a great piece of property. The problem is, it's so remote that there is no electric service available. One thing I noticed right away about my property is that most of the time, the wind is blowing. Let me state up front that I probably won't be able to help you out much if you decide to build your own wind turbine. Since no one seems to be reading the FAQ, I will answer the No. 1 question I get many, many times a day right here up front. Update: Here is a video of the wind turbine in operation. Update: Here is a video of me assembling and setting up the wind turbine on my remote off-grid property. I started the process of designing my wind turbine by Googling for information on home-built wind turbines. I reduced the project to just five little systems. for only $26. . Finally!

Raised Bed Gardening How To Guide For space efficiency and high yields, it’s hard to beat a vegetable garden grown in raised beds. Raised beds can improve production as well as save space, time, and money. They also are the perfect solution for dealing with difficult soils such as heavy clay. In addition, raised beds improve your garden’s appearance and accessibility. Raised gardening beds are higher than ground level, and consist of soil that’s mounded or surrounded by a frame to keep it in place. One reason raised beds are so effective for increasing efficiency and yields is that crops produce better because the soil in the beds is deep, loose, and fertile. Raised beds also save time and money because you need only dig, fertilize, and water the beds, not the paths.

Setting Up a Home Science Laboratory Part III – Chemicals on the Cheap This article is based on material originally published in Illustrated Guide to Home Chemistry Experiments: All Lab, No Lecture , by Robert Bruce Thompson, and the not-yet-published Illustrated Guide to Forensics Investigations: Uncover Evidence in Your Home, Lab, or Basement , by Robert Bruce Thompson and Barbara Fritchman Thompson. Laboratory chemicals are expensive, at least if you buy them from specialty lab supply vendors. Fortunately, there are many alternative sources for good quality, useful chemicals at reasonable prices. These alternative sources are many and varied, including the drugstore, supermarket, hardware store, or home improvement center, auto parts store, lawn and garden store, and pottery supply store. The purity of these chemicals ranges from very high (USP or FCC grades, intended for human consumption) to the lower practical and technical grades. Furthermore, you’re not limited to the chemicals offered for sale. Key Chemicals
